SP4 Severe Duty
Rugged cast-iron motors with NEMA Super Premium (IE4) efficiency, hazardous location certifications, and compliance with 2027 U.S. DOE MEM regulations.
The Next Evolution in Electric Motors
Leading the way in energy efficiency yet again, Baldor-Reliance® SP4 motors give you a path to energy savings that makes a difference to your bottom line. These motors achieve NEMA Super Premium efficiency across-the-line, independently of a drive. DOL or inverter duty, runs cooler, longer and quieter – now with a 48-month warranty.
The idea is simple. Take the best and proven AC induction design and make it better by reducing motor losses by an average of 20% while maintaining the simplicity of today's installed base of AC induction motors.

ABB’s SP4 technology meets the NEMA Super Premium® efficiency level in a standard AC induction motor design operating across the line, independently of a variable speed drive, or higher when powered by a VSD.
Large install base
There are more than 300 million industrial motor-driven systems in operation worldwide; and roughly 80% of motors still operate DOL (direct on line).Lower energy costs
NEMA Super Premium® (comparable to IEC’s IE4 efficiency) can offer up to 40% lower energy loss in comparison with a NEMA standard efficient (IE2) induction motor.Government compliant
Effective June 2027, Medium Electric Motors Rule driven by the Department of Energy will become effective. 100-250Hp industrial electric motor must increase to NEMA Super Premium /IE4 levels.Cooler running
Able to achieve cooler running operation for longer life which means longer bearing life. This translates to longer motor life and industry-leading 4-year warranty.Inverter Duty
